HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 748,862, dated January 5, 1904. Application filed December 17, 1902. Serial l lo. 135,598. (No model.)

To 02% whom it may concern.-

Be it known that I, CHARLES A. HAMMEL,a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to that class of hydrocarbon-burners in which oil and steam or compressed air are used as afuel and are commingled within the burner; and the object is to increase the efficiency and durability of the burner. I accomplish this object by the burner described herein and-illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of my burner complete. Fig. 2'is a perspective view of the burner-tip. Fig. 3 is a central vertical longitudinal section of the burner-tip. Fig. 4 is a front view of the upper rear portion of the tip. Fig. 5 is a View, looking up, of the upper portion of the tip.

In the drawings, A is the steam-supply pipe, which is connected to a suitable supply. (Not shown.) This pipe is screwed into the rear end ofsteam-chamber B, which chamber is in the lower member or base 0 of the casing of the burner-tip. The front face of the base is curved and near the front end projects upward and has a slight ofiset for the reception of the removable wearing-plate D, which plate forms the bottom of the mixingchamber E. Secured to the base-plate by screw -holts F, which screwinto holes G, is the rear top member H of the tip. in the lower face of this member is the steam-equalizing chamber I, which is in communication with the steam-chamber B through port J. Leading from this equalizing-chamber are three steam-ducts K, L, and M. The outer ducts are adapted to discharge the steam on lines that will intersect each other in the mixingchamber, which chamber is covered by the front top member N, which is secured to the base-plateby bolts 0, which screw into holes in the base-plate. These bolts pass through holes in the removabie'bottom wearing-plate D. The central steam duct decreases in depth from the equalizing to the mixing chamber, but is of the same width, its outlet being wide and flat. The object of this construction is for the purpose of having the full equalizing strength of the steam from the equalizing-chamber to break up and force the. oil through the intersection of the steampressure from the side steam-ducts. In the front top member is a recess broad and narrow at the front and decreasing in width, but increasing in depth, the side lines of which terminate on each side of the steam-ducts and nearly on a line with the top thereof. In each edge of the top portion of this recess is a channel 10 for the reception of the edge of the removable upper removablewearing-plate R, which is held against accidental displacement by the set-screws. The oil-pipe T, connected to asuitable supply, (not shown,) screws into an oil-chamber U, which chamber is connected by oil-duct V with the mixing-chamber. This oil-duct terminates between the side steam-ducts and over the central steam-duct, as shown most clearly in Fig. 4.. A steam by-pass W connects the oil and steam pipes, so that, if desired, the 0il-passages may be cleaned out with steam.

It will be observed that the general form of the burner-tip is very similar to Patent No. 640,328, issued to me on January 2, 1900; but in that patent there is a direct straight passage through the equalizing-chamber into the mixing-chamber, and the steam-duct under the oil-duct is of uniform size from equalizing-chamber to the mixing-chamber, which caused a loss of steam-pressure of the steam passing through this duct by reason of the friction on the sides of the ducts and also caused undue wear on the walls of the duct, which soon threw the ducts out of balance, thereby producing an uneven flame. The duct was also substantially square in crosssection. There were no removable plates to form the top and bottom surfaces of the mixing-chamber. I found in practice that the direct straight passage of the steam through the equalizing-chamber and into the mixingchamber was detrimental to the eificiency of the burner. I also found that the top and bottom surfaces of the mixing-chamber would be cut by the action of the steam and the impurities of the oil and that as soon as these surfaces were cut the flame was uneven andthe tip must be removed and replaced by a and connected therewith; an oil-chamber above the equalizing-chamber; a mixingchamber in front of said equalizing-chamber;

three ducts leading from said equalizingchamber into said mixing-chamber, the outer ducts being adapted to discharge steam in planes which meet in said mixing-chamber, and the central duct being wide and shallow at the front and deeper at the rear thereof; an oil duct terminating between the side steam-ducts and above the central steam-duct and connecting said oil-chamber with said mixing-chamber.

2. An atomizer formed of members fitted together, and having a chamber and an outlet-cavity between them, and means for atomizing and directing liquid from the outlet, and detachable wearing plates lining the walls of the outlet-cavity to guide the material to be discharged.

3. An atomizer having an outlet Cavity grooved in each corner, and removable wearing-plates in said grooves.

4. An atomizer having removable flat Wearingplates forming the walls of its outlet.

5. In a hydrocarbon-burnerhavinga cavity leading to the discharge-orifice of the bu rnertip, a removable wearing-plate in the top thereof.

6. In ahydrocarbon-burnerhavingacavity leading to the discharge-orifice of the burnertip, a removable wearing-plate in the bottom thereof, extending from end to end of the cavity and fixedly held and receiving upon its longitudinal surface the direct impact of the vapors.

7. A hydrocarbon-burner having a cavity leading to the discharge-orifice of the burnertip, and removable Wearing-plates in the top and bottom thereof said plates forming the wearing-surfaces of the top and bottom of said cavity.

In witness that I claim the foregoing I have hereunto subscribed my name this 10th day of December, 1902. I

CHARLES A. HAMMEL.
